Application Set-Ups And Io Connections - Danfoss AK-CC55 Compact User Manual

AK-CC55 Compact
AK-CC55 Compact is optimised for control of one evaporator plus different combinations of light, rail heat and alarm
relays.
It has 4 Digital Outputs (DO), known as DO1 – DO4, one Analogue Output (AO), known as AO1, 4 Analogue Inputs
(AI), known as AI1 – AI4, an input that can be used as either an AI5 or as a DI (Digital Input) DI1, and one Digital Input
(DI2).
It has 9 different application options (Application 1 – Application 9) to control the functions of the input and output
relays.

Application set-ups and IO connections

AK-CC55 Compact is designed for control of one evaporator + different combinations of light, rail heat and alarm
relays.
The most important variations are:
Applications 1-4: TEV applications
Control of compressor or solenoid valve, alarm relay, lights, rail heat
Application 4: Configurable outputs, e.g.: Dual compressor operation, heat function, night blind, ECO fan
Applications 5-9: EEV applications
Control of AKV valve, compressor, alarm relay, light, rail heat.
9: Configurable outputs, e.g.: Dual compressor operation, heat function, night blind, ECO fan
